TYPOGRAII-IICAL MACHINE.

This invention relates to improvements typographical machines providedwith a detachablematrix storage magazinetand the invention hasreference, more particularly, to an improved matrix locking device whichis mounted on the magazine as a permanent or non-separabie fixturethereof.

This invention has for its principal object to provide an improvedconstruction of matrix locking device in the form of a rotatable lockingbar which is assembled with the mouth or discharge end of the matrixstorage magazine in permanent relation thereto, and which, by simplerotative movement, may be brought into matrix locking or releasingposition at will, together with means to secure the bar in either suchlocking or releasing position; said rotatable locking bar is alsoprovided with a novel means adapted to cooperate with a magazine lockingdevice so as to release the iatter. for

disengagement with the magazine when the locking bar is turned to matrixlocking position, and so as to prevent manipulation thereof to unlockthe magazine while the locking bar is turned to and positioned in matrixreleasing position.

This invention has for a further object to provide such a constructionof rotary looking oar, that, when the same is rota-ted to matrix lockingposition, it will at the same time lift or retract the stored matricesto remove the weight of the same from the escapement devices of thetypographical machine.

Other objects of this invention, not at this time more p .rticularlyenumerated, will be clearly understood from the following detaileddescriptionof the same.

This invention is clearly iliustrated in the accompanying drawings, inwhich Figure 1 is a plan view of the discharge end portion of a matrixstorage magazine equipped with the novel rotary matrix looking of thisinvention, and showing the cooperative relation of said locking bar,while in matrix releasing position, with one style of m azine lockinglatch; Figure 2 is a transverse section, taken on line 2-2 in Figure l,but showing the cooperative relation of said locking bar, while inmatrix locking position, with said magazine locking latch; Figure 3 is afragmentary vertical c oss section,onan enlarged scale, taken throughthe discharge end of the magazine,

taken on line (i- 5 in Figure 1; Figure 6 is an end view, on an enlargedscale, of the cam member of the rotary matrix locking bar whichcooperates with the magazine locking latch; Figure 7 is fragmentary planview, onan enlarged scale,-of a' modified means for selectivelyretaining the matrix locking bar in either its matrix releasing orlocking position; and Figure 8 is a fragmentary plan View of anotherstyle of 'mag'azine locking l a'tch with which the rotary matrix lockingbar may be cooperatively associated. I

Similar characters of referenceare employed in the above described viewsto indicate corresponding parts.

Referring now to said drawings, the reference character 10 indicates amatrix storage magazine, in the upper and lower walls of which areprovided opposing guide grooves 11, in which the ears 12 of the matrices13 are engaged; each pair of opposed grooves 11 supporting a column ofmatrices 13 for downward feeding movement through and discharge from themagazine under the control of the usual escapement devices 14;. v

The upper wall of the magazine terminates a cover plate 15 which bordersthe discharge end thereof; ,Said cover plate possesses on its outerside, a transverse boss or enlargement 16. The under side portion ofsaid cover plate, in alignment with its boss or enlr. ement, istransversely bored to provide bearing seatl.'. for a rotary matrixlocking bar 18. Said locking bar 18 is thus mounted for rotation on itsiongitudinal axis, so that proper turning movements thereof willselectively position the same in eithermatrix releasing or lockingposition. That portion ofthe rotary locking bar lSwhich extends acrossthe series of matrix de grooves 11 of the upper wall of the azine, iscut awaytoprovide a flat face forming a matrix engaging abutment 19,which is shiftable, by rotation of the locking bar, either intosubstantially horizontal or substantia lyvertical planet relative to theplane of the magazine. lqVhen the locking bar 18 is turned in onedirection, viz, from left to right, said abutment 19 is shifted tosubstantially horizontal plane, so as to lie substantially'flush withthe bottoms of the upper guide grooves 11, thus being removed from thepath of movement of the upper matrix ea'rs through said upper guidegrooves 11, so that the matrices of each column or train thereof arefree for dis charge from the magazine under the control of theescapement devices 14 as shown in Figure When the locking bar 18 isturned in the opposite direction, viz, from right to left, said abutment19 is shifted to substantially vertical plane, so that one marginal edgeportion thereof is projected downwardly across the upper guide grooves11 and intothe path of movement of the upper matrix ears through thelatter, so that the rearward upper ears of the lowermost matrix of eachcolumn thereof will be engaged by said abutment 19 and discharge oroutward movement thereof from the magazine will be positively arrested,as shown in Figure 4.

The position of the rotary locking bar 18 relative to the escapementdevices 1%, when the magazine is operatively mounted on a linotypemachine, and the degree of turning movement imparted to the locking bar,when moving the same to matrix locking position, 'is such that, not onlywill the abutment 19 be projected into the above described matrixlooking or arresting position, but will also in moving to such positionexert an upward or inward moving pressure on the lowermost matrix ofeach column thereof, whereby the matrices are disengaged from theescape-- ment devices 14, thus removing the weight of the columns ofmatrices from the latter devices, and thereby obviating any risk ofinjury to the escapement devices when placing the magazine into serviceposition or removing the same therefrom. This mode of operation isclearly indicated in Figure 4. When the locking bar is turned to matrixreleasing position, the abutment 19, in moving away from the upper earsof the lowermost matrices, allows each column of the latter to slidedownward until said lowermost matrices are brought into opera tiverelation to the pawls of said escapement devices.

From the above description and an in-,

spection of the accompanying drawings, it will be clearly ap arent thatthenovel rotary matrix locking bar is mounted in connection with themagazine as a permanent or nonseparable part thereof. This is of decidedadvantage, as compared with the heretofore known slidably removablematrix locking bar commonly used in the matrix storage magazines oftypographical machines, since it is not, as is the latter, subject toloss or accidental distortion by rethereof readily yield, therebyobviating all lateral strains or stresses tending to distort or bend thematrix bodies or their ears,

which is the common accompaniment of ion gitudinally shiftable lockingbars provided with matrix lifting cam portions or the like operatingwith sidewiee sliding etfect'relative to the matrices. V

lieans are provided on an external end of the rotary locking bar 18 bothto manipulate it for turning movement, and to retain the same in itsrespective active'and inactive positions. In one form, as shown inFigures 1, 2 and of the drawings, this means comprises the followingarrangement and construction of parts. The rotary lockingbar 18 isprovided, preferably its right hand end, with a. square shank orequivalent. portion 20 of reduced cross-section, which in turn isprovided with a screw-threaded portion 21 projecting from its free end.ably engaged upon said square shank 19, so as to turn with the lockingbar 18, is the hub 22 of a knob or finger-piece 23. Extending axiallyinto the interior of said knob and its hub from the outer end thereof isa socket or bore 24. Screwed upon the outer extremity of said threadedportion 21 is a nut 25, and disposed around the shank 20 intermediatethe inner end of said socket or bore 24 and said nut 25 is a compressionspring 26. Secured to the adjacent end of said cover plate 15 to projecttoward the annular peripheral portion of the knob or finger-piece 28 isa stop-pin 27. Provided in the inward face of said annular periph eralportion of said knob or finger-piece are a pair of spaced stop sockets28 and 29 in which the freeend of said stop-pin may be selectivelyengaged. Preferably a shallow channel or guide groove 30 extends betweensaid stop sockets 28 and 29. The tension of the spring 26 holds the knobinwardly pressed with one or the other of its stop-sockets 28 and 29operatively engaged with. said stop-pin, to thereby in'nnovably retainthe rotary locking bar 18 in either its active matrix locking positionor its inactive matrix releasing position, as the case may be. Forexample, when the knob is turned from left to; right 'to-position thelocking bar in inactive position, the stop-pin 27 will be engaged in thestop-socket 28, thus immovably retainingthe locking bar againstaccidental displacement from said inactive lia position locking bar 18to active matrix locking position, the knob s3 is first drawn outwardlyagainst tie tension oi the spring to release its stopsoclret 28 fromoperative relation to said stop-pin 27, whereupon the knob may be turnedfrom right to left, thus turn- 7 ring the locking bar 18 to activematrixlocking position and registering the stop-socket 29 opposite thestop-pin 27, so that by releasing the knob the spring 26 will bring theformer into engagement with the latter, thereby retaining the lockingbar against accidental displacement from its aforesaid active matrixlocking position.

Referring now to Figure 7 of the drawings, there is illustrated therebyanother form of means for retaining the locking bar 18 againstdisplacement from either its active or inactive position, as the casemay be. in this latter form the outer end of the locking bar 18 isprovided with a knob or finger-piece 31 rigidly atlixed thereto andprovided with spaced stop soclrets similar in kind and arrangement tothose of the above firstdescribed construction. Slidably mounted in-theadjacent end of said coverplate 15 is a movable stop-pin 32, normallyprojected therefrom by a compression spring 33 which thrusts outwardlyupon its inner end, in such manner that the outer free end of saidstop-pin 32 may be selec tively engaged with the proper stop-socketaccordingly as it is desired to retain the locking bar in either activeor inactive position. Connectedwith and extending latorally outward fromsaid movable stop-pin through a suitable opening 3% provided in thecover plate boss 16, is a finger-piece 35, by means of which thestop-pin 32 may )e retracted and released from the knob 31 when it isdesired to manipulate the same in turning the locking bar 18 to activeor inactive position, as the case may be.

As heretofore mentioned, this invention also includes means, inconnection with the novel rotary matrix locking bar, whereby lockingdevices for locking the matrix stormagazine into a-linotype, machine may"be controlled in such manner as to prevent removal of the magazine fromthe machine until said matrix locking bar has been turned to activeposition to hold the matrices against escape from the magazine while thelatter is removed from the 'ma chine and during other hand ing thereof.hiag'azine locking devices of various kinds employed. One form of such mazine locking mechanism is illustrated in A igures l and 2, the "sameb'ein of that type which in erves bot to hold the escapement carryframe'36 in upwardly lifted operative e ion tothe magazine, and incident'lyto e lock the magazine against removal, this type or"lockingin'e'chanism bein of a islal ihen it is desired to turn the entth with one of said swinging arms 37 is a Slll'ir I ably siuoporte'dslidable bolt 39, haviiw a nosing 40 operatively engageable with a cess4:1 in the side of said swinging arm, to that, when thus engaged, saidswinging is retained against outward movement'permitti'n'gi thedisengagement of its latch 33 from locked relation to' the magazine.Operatively relatec'l' to said b01539 is a transversely 'slidable plate42 having an oblique cam portion 4-3 which coacts with a correspondingoblique slot in the body or? the bolt, whereby transverse movements ofsaidplate eilwill produce movements of saidbolt toward or away from theswingi arm 3'7 to engage or disengage the nosin the former from therecess of the latter, as Said slid-able plate is p the case may be.provided at its inner side with a chamfercd nose itagainst the rearwardside of which f tially alined to the axis of the rotary lock 'ing bar 18of magazine operativeiy mounted in the typographical machine. Fixed onthe left hand end of the rotary locking bar 18 15 a cam 46 having ahelical face 47 (see Figure lVhensaid matrix locking be hr 18 is turnedto inactive matrix releasing position,the helical cam face t? overhangsthe chamfered nose 44, as shown in Figure 1, thus permitting the springactuated movement of the slidable plate 1-2 to dispose the bolt 39 ininterlocked relation with the swinging arm 37, when the latter is inoperative inwardly swung position to en'- ga ge its latch 38 with themagazine. It will thus be evident that before the swine"- n, Q mg arm Brand its latch can he released from magazine locking" position, the bolt39 must first be retracted by an outwar movement of said slidahle plate42. T result is accomplished by turnin the the cam 46 to move itshelical face 4-7 against the ch'amfered nose 44itherebv pressing outwardthe siidable plate L2, thro 1' such movement of the latter ret the boltV will thus be appara-t eneethe maerixloeking bar T8 is turned to activematrix locking position, the swinging arm 37 will be released from therestraint of the bolt 39, so that it may be swung outward to remove itslatch 38 from locked relation to the magazine, and consequently uponrelease of the opposite latch also, the magazine may be removed from themachine, it being thus assured that the matrices contained therein aresafely secured against accidental outpouring or discharge therefrom,when the same is removed from and handled outside ofthe typographicalmachine.

In some older types of typographical machines, the magazines must firstbe lifted away from the escapement devices before it can be removed fromthe machine, and to this end the magazine is supported on a pivotedframe, which is upwardly swung by rotary cams 48 actuated by levers 49,generally indicated in Figure 8 of the drawings, and in a mannerfamiliar to those skilled in the art. In this type of machine the cams48 are locked against actuation, to thus prevent the raising of themagazine to a position freed from the escapement, and therefore subjectto rem-oval, by means of a spring pressed pivoted latch 50, mounted on,

one end of a fixed escapement carrying bar 51, which latch 50 engages astopprojection on the side of the adjacent cam 18. The tail portion ofsaid pivoted latch 50 is provided with a chamfered nose 53 which issubstantially alined to the axis of the r0- tary matrix locking bar 18,so that, when the magazine is engaged in operative position in themachine, and said rotary matrix locking bar is turned to inactive matrixreleasing position, the helical cam face 47 of the cam 46 of the latteroverhangs said chamfered nose 53. It will thus be evident that beforethe magazine can be raised to removing position, the latch 50 must beswung out of obstructing relation to the stop-projection 52. This resultis accomplished by turning the matrix locking bar 18 to active matrixlocking position, which movement rotates the helical face 47 of the cam46 against the chamfered nose of the latch 50 to thereby turn the latteron its pivot or fulcrum to released relation to said stop-projection 52.It will thus be apparent that the cams 48 will be released for actuationwhereby the magazine may be raised to removable position, it being atthe same time assured that the matrices contained therein are safelysecured against accidental outpourin or discharge therefrom, when thesame is removed from and handled outside of the mchine.

It will be obvious that various changes may be made in the generalarrangements and combinations of parts making up the instant inventionwithin the scope of the appended claims. Hence, I do not limit myself tothe exact arrangements and combina- 1,ess,oae

tions of the various devices and parts as above described in the foreoing specification, nor to the exact details thereof as illus trated inthe accompanying drawings, ex cept as may be required by the limitationsspecified in the appended claims.
